How to partition a harddrive

Hi, i have just bought a new laptop Windows 8 with a 750 harddrive but want to partition it safely. Is there a programme that is FREE that will do this? I used to partition with 'Partition Magic' will that still work safely and if so how do i convert megs i think, to Gigs? I am useless at conversion.
Many thanks

Windows 8 uses the same system as Window 7 and includes all the tools you need for partitioning your disk. Go to the Desktop, right click on Computer and left click on Managem followed by left click on Disk Management. All will be revealed....

Very many thanks Fruit-Bat, I have jumped from Vista to Win 8 so didn't know about that. I take it you think it is a good idea to partition to help stop virus' etc from messing up your important stuff?
Can you advise, is there any free programmes that would be good to install for safety? Or is the ones i have on the dying laptop ok? I have Microsoft Essentials and AVG.

Sorry Fruit Bat, you lost me. What is imaging and how do i do that?
My C drive is 127 gigs. Do you mean me to divide this up into sections? One for Programmes, one for OS and one for imaging?
I have the other drive for my data.
Thanks Fruit Bat
